I'm 34+5 and all day today I'm having severe cramping all the way down my left leg to where it hurts to walk.. I have also had a crazy increase in the amount of Charlie horse cramps as well. Last night I was having awful awful gas build up to where I was having all those weird gurrgling noises in my stomach. My son seems to be dropping very low so I don't know if that's what may be causing the cramping in my leg but its awful. :( also much increase in lower back pain.
